Dear all,
I am quite newbie, and I embarked on the construction of a QUAD Copter to learn about.
Frame: Tarot IronMan 650
ESC's: Castle Creation QUADPACK 35 with one embedded Bec
Motor: Motor T-MT4006
FC: 3.2 PixHawk
RC: Futaba 14SG - Mode3
After having done all the calibrations (ESC's, Accel, GPS, etc ....): Good
The quad "Armed" Disarmed and Correctly
First Test Flight: Crash (Flip Roll)
Symptoms:
1- What Was Supposed on RC to Yaw on right stick (Left / Right) Was Actually Pitch:-(... Then What Was Supposed to Pitch on left stick (Up / Down) Was Actually Yaw ...
2- What l'm suspicious about is entering ESC QUADPACK setup during Armed Process ... I Even Had to re-position Correctly low throttle value and Recalibrate radio to Avoid Any UNSYNC motor.
Now, l need admitted l'm quite lost in middle of nowhere cause After changing all parameters by interverting on Transmitter Function: Yaw / Pitch and re-cal Radio on Mission Planner look wich is totally unconsistent now. Cause Mission planner See Yaw as a Pitch and Yaw as Pitch...
I really feel very Frustrating misunderstanding something. Then of course you can imagine the last flight test result in Same crash :-(
First, Thanks to all of you read my post Who
Second, Will appreciate all the advise because really feel alone shithouse
Sincerely

First off, you clearly have either something mis-wired or the channel assignment on your Futaba is wrong. You'll have to straighten that out.
Second, you cannot normally calibrate Castle Creations Quad Pack ESCs. They come with factory set endpoints. You have to adjust the endpoints on your Futaba to match what the Castles use. For a description of this problem/feature, see this thread.
I would say you have a rather challenging build. I hope you aren't a beginner.....
Thank you Tom for your hand! Yes I am a beginner
1) Regarding the wiring, I just proceed (Mission Planner - Motor Test) to test motors if they were in the right order;
Test: Correct 1, 2, 3, 4 motors in right Order
Nota Bene: My ESC (Bec) is in 3rd position - Do not know if it has importance or not
2) I guess problem comes from: I did not properly Calibrate all ESC's one by one through my receiver but only Master ESC (including Bec) thinking it will manage other Slave ESC's. Guess I'm totally wrong.
3) To adapt my throttle calibration, l have just changed values in Futaba (ATV - GAZ: 135 104 119 135)
Which l guess allowed me to armed (improperly) the Quad.
For information, I do have CastleCreation usb cable
would you mine advise me the best way how to calibrated ESC's one by one.
Gratefully thanks for your help
I'm sorry if I wasn't being clear enough. You do not calibrate Castle Creations Multirotor ESCs. They are already calibrated at the factory to have a fixed response range. The usual ESC calibration procedure on the APM wiki will not work for them. You have to adjust the throttle endpoints on your RC transmitter to match the Castle ESCs. The thread I linked to in my previous post describes this.
Compared to "normal" ESCs this is something of a pain in the butt. But for me the benefits of the Castle's small size/weight and their build quality makes it worth it. But as much as I like Castles, I wouldn't recommend them for a beginner because of these extra hoops to jump through.
Hi Tom,
Thank you, I totally agree and sincerely appreciate your advises
Based on your advises, l re-calibrate RC properly on ESC's Endpoint and also correctly map the channels (mode3) as well through RCMAP (extended parameters).
Even so, by just giving just progressive Throttle stick my quad is Crashing repeatedly.
- (Quad facing me) It seems Motor4 started with a delay then caused a Crash (Flip Roll)
- (Rotate 180degree) It seems Motor3 started with a delay then caused a Crash (Flip Roll)
- Re-Calib. Accel. successfull
- But still Crash (Front Roll)
For Information:
- By choosing the Frame (X), I also loaded Params in Default Setting: Beginner.param
- I do not use PPM encoder and my Futaba receiver is directly connected to PixHawk pin: RCIN
- Also confirm my ESC's connections order as mentioned is respected as: Diagram attached

Make sure you have the correct frame, either X or + and if that does not help perhaps you have to re map your channels. http://copter.ardupilot.com/wiki/arducopter-parameters/#RCMAP__Para...
It might be best to start again and check everything piece by piece.
Don't try and fly if the channels are not mapped correctly.

Hi Gary,
Thanks for your comment
I'm facing 2 issues:
- Proper ESC's Calibration
- Mapping Channels
Your link, Surely will help me a lot especially Roll Channel assignment.
Actually cause i'm beginner l did Copy/Past and adapt a model (Mode3) is working well on DJI Wookong-M
Well was apparently wrong on Pixhawk...
